Sophisticated calibers like those in a AP-VC-Blancpain,can be quite solid.But they also have to look beautifull at the same time.So they are made with a different approach than say a Rolex,that is made with strength and easy service in mind.Generally a simple well made caliber will be more reliable,because there are less parts in it that can go wrong.My opinion is that the calibers you show here,are no where near a Rolex for strength or reliability.
                                         
If you want a really qualified answer to your question,you need to ask a watchmaker who is used to sevicing these watches.Another thing you should bear in mind,is that watches like the AP-VC-Patek etc etc,do not often get the hard use of other types of watches.Because of the prices,people tend to treat them gently I personally would never ever buy a high end watch,for hard use.
